液晶电视跌落测试动态脆值分析

Analysis of Dynamic Fragility of LCD TV in Drop Test

论述了液晶电视全瓦楞缓冲包装结构设计方案,并对跌落测试数据进行了分析,论证了缓冲衬垫在装配过紧或较松的情况下,包装件在跌落测试中会产生不同的冲击响应谱曲线。据此提出了动态脆值概念,利用反推法寻求了最适合的动态脆值,优化了产品缓冲包装设计。

The design scheme of corrugated board cushioning structure of LCD TV was introduced. Drop test was carfled out and the data was analyzed. It was proved that different SRS curves of drop test of package will be produced while the pad assembly is too tight or too loose. Accordingly the concept of dynamic fragility value is put forward and reverse method was used to seek the most appropriate dynamic fragility value to optimize cushion design of package.
